When rebuking Yisrael on the sin of the Golden Calf and other occasions where they subsequently sinned (See Pasuk 22), why did Moshe not include their rebellion at the Yam-Suf and their grumbling at Marah and at Alush?
Ramban: Because he was not concerned about sins that they performed before Matan Torah, 1 for which they were held less responsible than those that they performed after Matan Torah, when they entered into a B'ris with Hashem.
When discussing the sin of the Eigel ha'Zahav, Tav'eirah, Masah and Kivros ha'Ta'avah (in Pasuk 22), and the sin of the Meraglim (in Pasuk 23), all of which the current generation were not guilty (since they were either under age or not yet born), why did Moshe omit the sin of Ba'al Pe'or, the one sin of which they were guilty?
